“His hearings were a disaster. Everybody was looking forward to something that was going to be really productive,” Trump said Sunday morning on Fox & Friends. “And he didn’t win with those hearings. It was a total not-good for Republicans and for the country.”

Trump was referring to Gowdy’s Benghazi committee hearing where Democrat frontrunner Hillary Clinton was questioned for 11 hours on her email scandal and the 2012 terrorist attack in Benghazi, Libya, where four Americans were killed.

“I mean, beyond Republicans, it was very bad for the country,” Trump stated. “So I hope he does a lot better for Marco than he did for the Benghazi hearings. Because they were not good. That was not a pretty picture.”

Gowdy, R-S.C., announced he is set to campaign with Rubio in Iowa, and he called Rubio a “rock-solid conservative.”

“I’ve been seeing on Twitter many, many people extremely angry about the whole thing. Because, you know, Marco’s been very strong for amnesty and very weak at the border. And a lot of people are very upset with Trey Gowdy for doing that,” Trump added.

Trump also retweeted various tweets where people bashed Gowdy. One person called Gowdy a “loser” and another person said Gowdy “let Hillary get away with murder.”
